Currently, in an emergency where the power grid is a danger, first responders must wait for the power company to send an employee to disconnect the power. This is often the "golden hour" for medical help where the injured person or people can most be aided by medical personel.

The Naval Surface Warfare Center, crane Division has designed and patented a way to safely bring down the local electrical grid without permanent damage. The patented method and device for bringing down the power grid includes a specially packed shotgun shell that can be fired from a shotgun or a flare gun. The shell is packed with a metallic Mylar webbing that shorts out the power lines. This causes the circuit breakers at the transformer to shut down power. The outage is kept in a small area and the circuit breakers are easily reset by the power company when the emergency is over.

Advantages- Fast - Easy to carry or store- Easy to reset power grid
